Principle of operation
The anti-falling process: when the top end, the bottom end and the four side surfaces of the projector body 1 fall to the ground in the positive direction, the projector body firstly collides and contacts with the rubber sleeve 2, the kinetic energy is primarily reduced through the self buffering performance of the rubber sleeve 2, the anti-collision capacity of the projector body 1 is primarily improved, when the elasticity of the rubber sleeve 2 is not enough to offset the impact kinetic energy, the rubber sleeve 2 is compressed and deformed, and then the plurality of first balls 14 extend out of the corresponding reserved holes 21 to replace the situation that the rubber sleeve 2 is contacted with the ground, since the projector body 1 is not a regular object and is inclined when falling, the impact force received by the first balls 14 is not vertical upward, and therefore, the forward thrust is generated, the first ball 14 starts to roll by the forward thrust, and the self rolling is used for replacing the rigid collision between the projector body 1 and the ground, so that the anti-collision capacity of the projector body 1 is further improved;
the installation step:
firstly: the two rubber sleeves 2 are sleeved on two sides of the projector body 1 respectively, the four rubber clamping strips 3 are placed at the top end and the bottom end of the projector body 1 respectively, the rubber inserting pieces 22 at two ends of the two rubber sleeves 2 are inserted into the strip-shaped inserting grooves 31 of the corresponding rubber clamping strips 3 respectively, eight first screws 34 are screwed down respectively, and the rubber clamping strips 3, the rubber inserting pieces 22 and the rubber sleeves 2 are fixedly installed on the outer side wall of the projector body 1;
secondly, the method comprises the following steps: taking down one supporting rod 8 from the placing groove 15, installing one end with external threads in the threaded cylinder 49 in a threaded manner, selecting the number of the supporting rods 8 according to outdoor projection environment and projection requirements, installing the supporting rods 8 in a head-tail threaded manner through threaded connectors 81, and selecting the type of a supporting base according to the outdoor projection environment and projection requirements;
if the ground is flat, smooth and hard, the first base 5 is suitable to be selected, because the contact area between the first base 5 and the ground is large, the fourth screw 71 below the first base 5 is directly rotated, the corresponding rotating sheet 72 is driven to rotate, and simultaneously, the top end of the fourth screw 71 is separated from the top of the placing groove 15, and then the fourth screw 71 is installed on the threaded connector 81 at the lowest part in a threaded manner;
for example, the second base 6 is suitable for being selected when the ground is rough and muddy, because the second base 6 adopts a mode of inserting four supporting oblique rods 63 to improve the supporting stability of the device, in consideration of the complex supporting environment, four small holes 61 need to be formed in the top end and the bottom end of the second base 6, mounting rods 62 are slidably mounted in the four small holes 61, the bottom ends of the four mounting rods 62 are fixedly connected with the supporting oblique rods 64, the height of each supporting oblique rod 64 is adjusted by adjusting the positions of the mounting rods 62 inserted into the corresponding small holes 61, finally, the top ends of the fourth screws 71 fall off from the groove top of the placing groove 15 by screwing the mode of screwing the third screws 66 and pressing and contacting the corresponding mounting rods 62 through the limiting pieces 65 to ensure that the supporting oblique rods 64 are pressed and fixed, directly rotating the fourth screws 71 below the second base 6 to drive the corresponding rotating pieces 72 to rotate, then, the fourth screw 71 is screwed on the threaded connector 81 at the lowest part;
thus, the selection and installation of the base are completed;
and finally: the method comprises the following specific operation steps of adjusting the projection position of a lens of the projector body 1 according to the position of a projection curtain:
because the second ball mounting seat 41 is fixedly mounted with the projector body 1, it is desirable that the adjustment of the projector body 1 can be realized by adjusting the second ball mounting seat 41, and it is desirable that the second ball mounting seat 41 can be realized by relative rolling of the second ball mounting seat 41 and the second ball 43, because the bottom end of the second ball 43 is fixedly connected with the threaded cylinder 49, and the threaded cylinder 49 is fixed on the ground through the supporting rod 8, the threaded connector 81 and the first base 5 or the second base 6, on the premise that the second ball 43 is not moved, the second ball mounting seat 41 is rotationally and rollingly adjusted, until the lens of the projector body 1 is opposite to the position of the projection screen, the two second screws 47 are respectively screwed, the second ball 43 is limitedly pressed through the arc-shaped pressing piece 46, and it is ensured that the second ball 43 and the second ball mounting seat 41 are relatively stable.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
